Which complex number is a distance of sqrt17 from the origin on the complex plane? a. 2 + 15i b. 17 + i c. 20 - 3i d. 4 - i

Let z=x+iy be a complex number. The distance from this complex number to the origin is

Consider all options:

A. z=2+15i, then

B. z=17+i, then

C. z=20-3i, then

D. z=4-i, then

correct choice is D.

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
